  1. What's new in this club
  2. Thanks for the tip. Good article
  3. My Mac was infected by an adware called anysearchmanager, but Malwarebytes can't help. I removed it from this article: https://www.securemacos.com/remove-search-anysearchmanager-com-virus-from-mac-os/
  4. So how to locate or update or refresh or rescan iTunes library? Easy-Fast way (not always successful) First quit iTunes app. Re-launch iTunes app while holding down the Option key. Select “choose library.” Go the iTunes folder and choose it. Another method that always works for me (just takes forever) Launch iTunes app on your computer Navigate to File -> Add to library Select the location of your iTunes library (ex: iTunes folder) iTunes app will relocate or refresh all meta data and files you already have to library. Don’t worry it won’t recreate duplicate files.
  5. This is what I did... On the Watch: Go to General --> Settings --> Reset --> Erase All Content and Settings Let the Watch reset back to basically the state that it came in when it first arrived. Pair the Watch again to the iPhone: Open the iPhone app and pair it to my Apple Watch. Restored my Watch from the back-up. Put my Watch on the charger. Opened the Apple Watch app and applied the update from my iPhone.
  6. Anytime I try and upgrade my iWatch it says it can't because there is no internet connection. I verified I have internet connection. I also went to airplane mode and just had WiFi and Bluetooth, validated my internet (WiFi) worked and still won't upgrade. Any ideas?
  7. Very True yet the number of viruses, adware and spyware for other operating systems is typically much higher than the Linux based Mac OS. The facts are: There is no anti-malware software that can detect 100% of the malware out there. There is no anti-malware that can detect everything targeting the Mac. The very best way to prevent the most attacks is for you as the user to be aware that the most successful malware attacks rely on very sophisticated social engineering techniques preying on human avarice, ****, and fear. Internet popups saying the FBI, NSA, Microsoft, your ISP has detected malware on your computer is intended to entice you to install their malware thinking it is a protection against malware. Some of the anti-malware products on the market are worse than the malware from which they purport to protect you. Be cautious where you go on the internet. Only download anything from sites you know are safe. Avoid links you receive in email, always be suspicious even if you get something you think is from a friend, but you were not expecting. If there is any question in your mind, then assume it is malware
  8. Unfortunately everything changes. Today Mac OS is not so secure. This article describes Safe Finder virus from Mac http://macsecurity.net/view/124/

  10. You can change the system preferences for JoinMode and JoinModeFallback to be the following: JoinMode (String) Automatic Preferred Ranked Recent Strongest JoinModeFallback (String) Prompt JoinOpen KeepLooking DoNothing Do this using the airport command: /System/Library/PrivateFrameworks/Apple80211.framework/Versions/A/Resources/airport Run the command to see the options, up the top you'll see a section on how to sec preferences. $ /System/Library/PrivateFrameworks/Apple80211.framework/Versions/A/Resources/airport prefs AirPort preferences for en0: DisconnectOnLogout=NO JoinMode=Strongest JoinModeFallback=DoNothing RememberRecentNetworks=YES RequireAdminIBSS=NO RequireAdminNetworkChange=NO RequireAdminPowerToggle=NO WoWEnabled=YES An example of updating the JoinMode from Automatic to Strongest sudo /System/Library/PrivateFrameworks/Apple80211.framework/Versions/A/Resources/airport prefs JoinMode=Strongest Also a helpful feature is to turn on debugging sudo /System/Library/PrivateFrameworks/Apple80211.framework/Versions/A/Resources/airport debug +AllUserland +AllDriver +AllVendor +LogFile This can all be found by just running airport with no options after
  11. Check out this link from Cisco http://www.cisco.com/c/en/us/td/docs/wireless/controller/technotes/8-2/b_Enterprise_Best_Practices_for_Apple_Devices_on_Cisco_Wireless_LAN.pdf Navigate to WLANs > Security tab of the WLAN and check both FT and non-FT authentication. Example 802.1X and FT 802.1X, or PSK and FT-PSK. Non-802.11r clients which have the updated wireless LAN drivers for '802.11r-compatibility' can now join this 802.11r-mixed-mode WLAN. It is important to note that laptop clients with newer wireless LAN chipsets and updated chipset drivers with 11r-compatibility, both are equally important when trying to use the 11r mixed-mode SSID configuration. For example, Apple introduced the 11r-compatibility drivers for the MacBook Laptops with their Mavericks 10.9 OS, which allowed the MacBook to correctly identify and associate to a mixed mode SSID (e.g. FT-PSK + PSK). Any MacBook laptop running an older OS (even with the same chipset) might be able to see the 11r mixed mode SSID, but may fail to associate to it. Also I tried running the following command that was suggested on airheads sudo defaults write /Library/Preferences/com.apple.airport.opproam disabled -bool true
  12. For system administrators, OS X roaming helps your Mac stay connected as it moves between different places within your office wireless network. Trigger threshold The trigger threshold is the minimum signal level a client requires to maintain the current connection. OS X clients monitor and maintain the current BSSID’s connection until the RSSI crosses the -75 dBm threshold. Once that threshold is crossed, OS X initiates a scan to find roam candidate BSSIDs for the current ESSID. Consider this threshold in view of the signal overlap between your wireless cells. For example, if 5 GHz cells are designed with a -67 dBm overlap, but OS X maintains a connection until the -75 dBm threshhold, those clients will remain connected to the current BSSID longer than you expect. Also consider how the cell overlap is measured. The antennas on computers vary from model to model, and they see different cell boundaries than expected. It's always best to measure using the target device. Selection criteria for band, network, and roam candidates OS X always defaults to the 5GHz band over the 2.4GHz band, as long as the RSSI for a 5GHz network is -68 dBm or better. If multiple 5GHz SSIDs meet this level, OS X chooses a network based on these criteria: 802.11ac is always preferred over 802.11n or 802.11a 802.11n is always preferred over 802.11a 80 MHz channel width is always preferred over 40 MHz or 20 MHz 40 MHz channel width is always preferred over 20 MHz OS X does not support 802.11k. Although OS X does interoperate with SSIDs that have 802.11k enabled, OS X doesn't limit roam scans of the environment based on the neighbor report. A roam scan is when stations check the available channels in a given band (either 2.4 or 5 GHz) for access points (APs) that support the current ESSID. OS X selects a target BSSID whose reported RSSI is 12 dB or greater than the current BSSID’s RSSI. This is true even if the OS X client is idle or transmitting/receiving data. Roam performance Roam performance describes how long a client needs to authenticate successfully to a new BSSID. Finding a valid network and AP is only part of the process. The client must complete the roam process quickly and without interruption, so the user doesn't experience downtime. Roaming itself involves the client authenticating against the new BSSID and deauthenticating from the current BSSID. The security and authentication method determines how quickly this can be achieved. 802.1X-based authentication requires the client to complete the entire EAP key exchange before it can deauthenticate from the current BSSID. This might take several seconds, depending on the environment’s authentication infrastructure, and translates into interrupted service to the end user in the form of dead air. OS X supports static PMKID (Pairwise Master Key identifier) caching to help optimize roaming between BSSIDs in the same ESSID. OS X doesn't support Fast BSS Transition, also known as 802.11r. Deploying additional SSIDs to support OS X isn't necessary because OS X interoperates with 802.11r. Measuring Client RSSI OS X offers a few easy, built-in tools for scanning to measure RSSI. To learn the RSSI for the currently associated network, hold the Option key while clicking the Wi-Fi menu in the menu bar. To learn the RSSI for networks in the client’s environment, use Wireless Diagnostics. To open Wireless Diagnostics, Option-click on the Wi-Fi menu, then selecting Open Wireless Diagnostic. When Wireless Diagnostic opens, choose Scan from the Window menu. Click the Scan Now button in the Scan window to find all nearby wireless networks and measure their RSSI. In addition to this graphic tool, the command-line utility "airport" found in /System/Library/PrivateFrameworks/Apple80211.framework/Versions/A/Resources/airport can be used to acquire the same data. The ‘-s’ flag scans the current environment for available networks and lists the RSSI, among other details. Starting with OS X El Capitan, you can turn on Wi-Fi Monitor on the desktop to display signal strength and other environment details. Hold down Option and Shift-click on the Wi-Fi menu to reveal the Debug menu, then choose Show Wi-Fi Monitor.
  13. iOS Roaming Trigger threshold The trigger threshold is the minimum signal level a client requires to maintain the current connection. iOS clients monitor and maintain the current BSSID’s connection until the RSSI crosses the -70 dBm threshold. Once crossed, iOS initiates a scan to find roam candidate BSSIDs for the current ESSID. This information is important to consider when designing wireless cells and their expected signal overlap. For example, if 5 GHz cells are designed with a -67 dBm overlap: iOS uses -70 dBm as the trigger and will therefore remain connected to the current BSSID longer than you expect. Review how the cell overlap was measured. The antennas on a portable computer are much larger and more powerful than a smartphone or tablet, so iOS devices see different cell boundaries than expected. It is always best to measure using the target device. Roam scan A roam scan is when stations check the available channels in a given band (either 2.4 or 5 GHz) for access points (APs) that support the current ESSID. The time it takes to scan depends on a variety of factors, but the best way to streamline this process is to enable 802.11k on your control plane since iOS leverages the first 6 entries in the neighbor report and reviews the candidates to prioritize its scanning. Without 802.11k iOS has to scan more methodically, potentially adding several seconds to the discovery process. For example, if a user is on a call and walks to the other side of the building, the device crosses the -70 dBm threshold and looks for roam targets. Using the neighbor report provided by 802.11k, it knows there are APs supporting the current ESSID on channels 36, 44 and 11. It immediately scans those channels, finds the AP on channel 44 has the appropriate signal strength, and roams. However, without 802.11k the client must scan all of the various channels on each band to find a roam target, adding several seconds to the process. Roam candidate selection criteria iOS 8 and later selects target BSSIDs based on two criteria: Is the client transmitting or receiving a series of 802.11 data packets? The difference in signal strength against the current BSSID’s RSSI. iOS 8 and later selects target BSSIDs whose reported RSSI is 8 dB or greater than the current BSSID’s RSSI if the client is transmitting or receiving data. Clients not sending or receiving data, for example sitting idle in a pocket, use a 12 dB differential. For example, if the RSSI of the current connection drops to -75 dBm, and the user is engaged in a VoWLAN call, then iOS 8 searches for BSSIDs with an RSSI of -67 dBm or better. If that same user isn't in a call, or transmitting or receiving a series of data packets, then iOS 8 only considers BSSIDs with an RSSI of -63 dBm or better. 802.11 Management and Control frames do not count as data. Understanding the selection criteria of iOS allows administrators to reevaluate their current wireless design to make sure that it provides the expected and required performance to support real-time services like voice or video. Roam performance Roam performance indicates the time a client requires to successfully authenticate to a new BSSID. Finding a valid roam candidate is only part of the process—the client has to actually complete the roam process quickly and unobtrusively so the user experiences no interruption in service. Roaming itself involves the client authenticating against the new BSSID and deauthenticating from the current BSSID. The security and authentication method dictates how quickly this can be achieved. 802.1X-based authentication requires the client to complete the entire EAP key exchange before it can deauthenticate from the current BSSID. This can take several seconds, depending on the environment’s authentication infrastructure, and translates into interrupted service to the end user in the form of dead air. The best way to streamline this process is to utilize the fast roam capabilities of 802.11r if this is supported by your networking equipment. 802.11r allows clients to pre-authenticate against potential access points, reducing the authentication time from potential seconds to milliseconds. Measuring Client RSSI using AirPort Utility Apple’s AirPort Utility for iOS 1.3.4 includes a wireless scanning feature that provides a log of the client’s view of the network. Administrators can use this feature to validate the iOS client’s view of the network at a given location or walking a path as the scanner maintains a log of scan events for review. Don't attempt to use AirPort Utility on the same device that you're running your application as that can produce inaccurate results. Apple recommends using a separate device (of the same model) dedicated to the scanning process. The scanning feature is enabled in the AirPort preferences pane in the iOS Settings app. Cached Roaming with WPA2-Enterprise.pdf
  14. Sometimes its helpful to know what ports on your Mac are in LISTENING status. So here are a few commands that I found helpful in my quest to find what ports are open. $ netstat -atp tcp | grep -i "listen" tcp4 0 0 *.irdmi *.* LISTEN tcp4 0 0 localhost.49155 *.* LISTEN tcp4 0 0 localhost.49154 *.* LISTEN tcp4 0 0 localhost.49153 *.* LISTEN tcp4 0 0 localhost.49152 *.* LISTEN tcp4 0 0 *.kerberos *.* LISTEN tcp6 0 0 *.kerberos *.* LISTEN tcp4 0 0 *.ssh *.* LISTEN tcp6 0 0 *.ssh *.* LISTEN tcp4 0 0 localhost.ipp *.* LISTEN tcp6 0 0 localhost.ipp *.* LISTEN tcp4 0 0 *.rfb *.* LISTEN tcp6 0 0 *.rfb *.* LISTEN And also I used $ sudo lsof -i -P | grep -i "listen" Password: launchd 1 root 26u IPv6 0x6a234a812945c29f 0t0 TCP *:5900 (LISTEN) launchd 1 root 28u IPv4 0x6a234a81294621ef 0t0 TCP *:5900 (LISTEN) launchd 1 root 30u IPv6 0x6a234a812945c29f 0t0 TCP *:5900 (LISTEN) launchd 1 root 31u IPv4 0x6a234a81294621ef 0t0 TCP *:5900 (LISTEN) launchd 1 root 43u IPv6 0x6a234a812945b89f 0t0 TCP *:22 (LISTEN) launchd 1 root 46u IPv4 0x6a234a812946104f 0t0 TCP *:22 (LISTEN) launchd 1 root 52u IPv4 0x6a234a812946191f 0t0 TCP localhost:631 (LISTEN) launchd 1 root 53u IPv6 0x6a234a812945bd9f 0t0 TCP localhost:631 (LISTEN) launchd 1 root 54u IPv6 0x6a234a812945bd9f 0t0 TCP localhost:631 (LISTEN) launchd 1 root 55u IPv6 0x6a234a812945b89f 0t0 TCP *:22 (LISTEN) launchd 1 root 56u IPv4 0x6a234a812946104f 0t0 TCP *:22 (LISTEN) launchd 1 root 59u IPv4 0x6a234a812946191f 0t0 TCP localhost:631 (LISTEN) pma_agent 70 root 19u IPv4 0x6a234a812945db6f 0t0 TCP *:8000 (LISTEN) bcua-serv 76 root 16u IPv4 0x6a234a812945e43f 0t0 TCP localhost:49154 (LISTEN) bcua-serv 76 root 19u IPv4 0x6a234a812945feaf 0t0 TCP localhost:49155 (LISTEN) mtmfs 79 root 4u IPv4 0x6a234a812945f5df 0t0 TCP localhost:49152 (LISTEN) mtmfs 79 root 6u IPv4 0x6a234a812945ed0f 0t0 TCP localhost:49153 (LISTEN) kdc 96 root 6u IPv6 0x6a234a812945b39f 0t0 TCP *:88 (LISTEN) kdc 96 root 8u IPv4 0x6a234a812946077f 0t0 TCP *:88 (LISTEN)

  16. With the introduction to El Capitan they removed the disc burning ability from the Disk Utility which is where most of us went to burn an image. So from El Capitan (10.11) and newer (or until they change it again) the below will be the way to do it. But no worries, they didn't take it completely away, more of relocated it. Open Finder and click once to highlight the image you want to burn. Then click Burn Disk Image "blah blah blah" to Disc... the Burning process will begin.. as long as you have your blank media in the drive. [attachment=0]2015-12-28_09-44-33.jpg[/attachment] Now if you prefer the reliable command line or otherwise referenced as the cli (command line interface) then open up Terminal and type the following hdiutil burn ~/Path/To/DiskImageFile.iso That's all there is to it.
  17. There comes a time that the DNS server(s) do not have the name to address resolution you need so just add it to your local hosts file. Mac OS X 10.2 or later Edit the /private/etc/hosts file. For more information on how to use the hosts file, open Terminal and type: man hosts Note: Editing this file requires root privileges. I suggest typing while in Terminal sudo nano /private/etc/hosts It may be a good idea to flush the DNS Cache that is running by then typing the following after you save the hosts file dscacheutil -flushcache
  18. Switching operating systems is a scary and can be exciting adventure. It can also be a major pain in the butt. I am not author of any book but hope I can help fill in some blanks. If you want a recommendation on a book, for beginners I strongly recommend a book called Teach Yourself VISUALLY Mac OS X Leopard It has proven itself to people of all ages on getting up and going with there move from Windows to Mac. Here are some basic things you may or may not know. Open Applications... In Windows you click the Start button - Click on Programs - Select Your Application In Mac OS X you click the Finder (looks like a smiley face) - Click on Applications - Select Your Application Check Email without having to purchase any additional application... In Windows you click on Outlook Express In Mac you click on Apple Mail (both are equal in functionality, Apple Mail seems to handle large amount of mail quite a bit quicker to include searching) Check Email with purchase of additional application... (mostly for us business people that need to connect to Outlook Exchange servers) In Windows you open Microsoft Outlook In Mac you open Microsoft Entourage (Microsoft Outlook is better but not be a whole lot. Entourage sync's with Outlook Exchange server to include Mail and Calendar without any issues) Word Processor included with operating system In Windows you click Start - Programs - Accessories - either Notepad or Wordpad In Mac OS X you click the Finder (looks like a smiley face) - Click on Applications - TextEdit (note that all Mac Applications are found in the exact same place... Finder - Applications unless you move them somewhere else) (I'll keep adding to this article so it will probably never be finished)
  19. I am curious as to what I should do when I can not click on FInder (it just makes a sound everything I click on it like something is in the background waiting for me to answer it but I can't seem to find anything). I can not open a new window and I'm not able to click on the apple to do a restart. Someone said to open terminal and type something like: sudo -h shutdown now but i can't get to Terminal. You could click on spotlight and type Terminal and it will find it for you at which time you could just double-click on. As far as shutting down or restarting your system you could do either without clicking on the apple, just as long as you can open up your terminal window. Reboot sudo -h reboot Shutdown sudo -h shutdown now[/code] NOTE: you will need your password Reference: Mac OS X Manual Page For sudo(8)
  20. One way to store or group files on a Mac is to create a Disk Image. A Disk Image is a file which has the properties of a separate hard drive or CD. It has a size limit and options for encryption to keep your files safe and secure. This how-to will work with Mac OS X. Steps Create a New Folder and place the files you would like in your disk image into this new folder. Right click (or CTRL-Click) the folder and select "Get Info" and note the size of it's contents. Open Disk Utility (Applications > Utilities > Disk Utility) Click the "New Image" icon to create a new disk image. Enter a name for the Image, and select a size adequate for the size of your folder you created in Step 2. Set the encryption to "none" and Format to "read/write disk image". See Tips to learn how to encrypt the image. Place the contents of the folder from Step 2 into the newly mounted disk image Unmount the Disk Image by dragging it's icon to the Trash. In the Finder window, you can also click the Eject symbol next to the mounted image. Be proud that you now know how to do something most people don't know how to do! Tips You can encrypt your Disk Image with a password if you would like your files to be private. Simply Select "AES-128" under the "Encryption" drop-down menu. After you click "Create" and it will ask you to create a password for your files. When you double click a .dmg file, it will "Mount" on the desktop. This is the only way to access or modify the contents of the Image. A .dmg file can be a very easy way to send files from one Mac to another. Any Mac can mount and access the Disk Image on their computer.
  21. Your bad kitty will run faster and smoother after it sheds a few gigabytes. A slimmer cat is a faster cat, and we'll bet dimes to DIMMs that you can shed several gigabytes from your Mac's hard drive without missing them. If you installed the default Mac OS10.4, for example, you've got 1GB of foreign language translation support, 2.1GB of printer drivers, and 9.9GB of bundled software. Once you've removed the biggest offenders post facto by following the steps below, take an hour to browse your hard drive for such junk as sample or stock images in Photoshop and sample songs in GarageBand (they're in /Users/username/Music/), and of course,s cour your iTunes library for all the podcasts that you forgot you subscribed to and other unwanted audio debris. If you use iMovie or GarageBand, archive or otherwise offload old projects, which are often huge. Applications Remove any expired demo software and any apps that you're not likely to use -- especially if you have the original installer discs. Games tend to fill loads of disc space, but only remove them as a last resort. Remember, all work and no play.... Printer Drivers The /Library/Printers folder holds hundreds of drivers that you'll never use, and two that you might use someday -- which will come with the printer and are available free at the manufacturer's website anyway. Application Support iLife themes from iMovie and iDVD consume virtual acres, some of which you can surely do without. Browse the themes in each app, make note of the keepers, then proceed to /Library/Application Support/ for a weed-out session. While you're in Application Support, remove any folders for apps that you've deleted, and feel free to browse the remaining folders for superflucous sample projects, tutorials, and the like. Also check /Users/username/Library/Application Support for redundant items that are already in the main Application Support folder, orphaned support files, and other dead weight. Language Support Mac OS X's localization support is unmatched -- but how many foreign languages are you ever going to use? Strip it down to your native tongue with Monolingual (free, monolingual.sourceforge.net) -- just read the included directions and make sure that you don't remove your native language. English-speaking 'Mericans should keep both English and (United States). And if you use Adobe CS apps, open Monolingual's Preferences and add them to the blacklist of apps that you want Monolingual to leave alone -- for reasons unknown, current versions of Photoshop et al won't run without full lanugage support. Bad Music The folder /Library/Audio/Apple Loops For GarageBand contains over 1GB of loops for GarageBand projects; we punted just the stuff that gives us violent urges (Club Dance Beat and so on), thereby freeing up a couple hundred megabytes. Shared Files If you maintain a multiuser Mac, keep track of what each user installs and where. If several users tinker in GarageBand, for example, in the name of congeniality and preventing duplicates they should install any additional loops for all users rather than only for their account. And you know they won't unless you tell them to. Same thing goes for any application or its add-ons.
  22. Tweak processor priorities and RAM usage where available Mac OS X is a masterfully multithreaded system with the ability to run and manage hundreds of tasks simultaneously, including tasks that you've initiated (a Final Cut Pro render, a Photoshop filter, a spell-check in Word -- anything) as well as oodles of background daemons, enless Spotlight indexing, and other noise. It's your Mac, so you get to decide which apps get processor priority and when -- it's known as niceness in the Unix world. Make iMovie nicer as it chews on your epic film while you write your acceptance speech in Word, or lash Photoshop to morrings of your specifications if that's where you spend the day. Process Wizard (free, La Chose : web agency and software maker ? agence web et développement de logiciels) provides handy sliders for you to addjust the niceness of any process running on your Mac -- or to kill a process outright, which can lead to mayhem, so proceed with caution. Process Wizard doesn't show you how much juice any specific task is sucking up, so launch Activity Monitor (/Applications/Utilities), click the CPU tab for a live readout of what processes are consuming how much of your processor(s), and use that information to adjust processor priority. Allocating RAM isn't generally as easy, but many RAM-hogging apps, such as Photoshop, provide a preference setting that you can tweak to give it the lion's share of your RAM.
  23. The Mac is rightfully revered for the beauty, power, and simplicity of its graphical user interface. Indeed, it was the release of the first Macintosh that brough the concept of pointing and clicking to the average computer user. But in addition to the point-and-click ease of the OS X Finder, your Mac sports on of the most powerful command-line interfaces on the planet: the Terminal. Mac OS X comes with hunderds of Unix programs - and you can get them all through the Terminal. As much as we love the ease of the GUI, the power of the Terminal is hard to beat. It allows you to do many things faster than you could using the GUI - and in some cases, it even lets you do things you can't otherwise do on your Mac. alias Create an alias alloc List used and free memory awk Find and Replace text within file(s) basename Convert a full pathname to just a folder path bash Bourne-Again SHell (Linux) bless Set volume bootability and startup disk options. break Exit from a loop cal Display a calendar case Conditionally perform a command cat Display the contents of a file cd Change Directory chflags Change a file or folder's flags. chgrp Change group ownership chmod Change access permissions chown Change file owner and group chroot Run a command with a different root directory cksum Print CRC checksum and byte counts clear Clear terminal screen cmp Compare two files comm Compare two sorted files line by line complete Edit a command completion [word/pattern/list] continue Resume the next iteration of a loop cp Copy one or more files to another location cron Daemon to execute scheduled commands crontab Schedule a command to run at a later date/time cut Divide a file into several parts date Display or change the date & time dc Desk Calculator dd Data Dump -

  24. nmap is the key... If you do not have nmap installed, then I suggest installing it. The best way to get this installed is using a program called fink. Note: You'll need to enable root user for nmap to work and know root password Once installed, open a terminal window and type fink install nmap (you'll have to type in your password just like you do when you install any program) Now that nmap is installed, run the following command nmap -sP -T Insane You should get an output like: You can also run Check out the GUI version of nmap for your Mac called Zenmap (most excellent tool)
  25. The goal here would be to ping an IP stored in a .csv file I found the following that may work machineName, MachineIP dozer, dozer2, dozer3, i=0; for $line in `cat spreadsheet.csv`; do ip=`echo $line | cut -f2 -d","`; if [ $i -ne 0 ]; then if [ `ping $ip -c1 | grep -c -i "64 bytes from ${ip}"` -eq 0 ]; then .... else echo "$ip could not be pinged" >> /var/log/mylogfile; fi fi i=1; i is used as the 1st line of the csv is headers.
  26. I realize I could use the Network Utility to do most of what typical troubleshooting does but I am more familar with the command prompt. When I use Windows I run my ping, tracert, nslookup, nbtstat, netstat and ipconfig. I would like to know the common commands I would use on my lovely mac for the same functionality and then some. So in short, compare the Apple Mac OS X Network Utility and Windows command prompt to what I can do in the terminal to match or beat what the others offer (which I know it can). Okay, tall order but I believe I can get this started. Network Utility - Info Mac OS X: $ifconfig Network Utility - NetStat: $netstat Display routing table information: $netstat -r Display comprehensive network statistics for each protocol: $netstat -s Display multicast information: $netstat -g Display the state of all current socket connections: $netstat -ta Network Utility - Appletalk: Network Utility - Ping: $ping or $nmap -sP -T Insane (for an entire range) Network Utility - Lookup: $nslookup > server name server delivering the response > set type=mx mx will lookup all mail records > microsoft.com machine being looked up Truthfully dig is a better command to use here instead of nslookup Network Utility - Traceroute: $traceroute Network Utility - Whois: $whois bbc.co.uk -h whois.nic.uk bbc.co.uk is who we are trying to find out about whois.nic.uk is the whois server we are using. Network Utility - Finger: $finger dennis or $finger mywiseguys@gmail.com Network Utility - Port Scan: $stroke host start_port end_port or $netstat -a or $nmap -Up 143
